Vermeer again - another way to test the fakes

Following koukhto Vermeer puzzle.

Interesting article about Vermeer's use of lens and camera obscura. I think that was known quite for some time already (His teacher Carel Fabricius also possibly used it, which is seen in one of his "curved" paintings.)

Vermeer's camera web-site.
Curious connection between Vermeer and Leeuwenhoek, the famous microscopist, born the same year (1632) in Delft.
(BTW I wonder if we can see rotifers in our toy microscope...).
Another article (but in French).
